2016-06-08don't explicitly configure the last round of packagesDavid Kalnischkies
We end our operation by calling "dpkg --configure -a", so instead of running a (big) configure run with all packages mentioned explicitly before this, we simply skip them and let them be handled by this call implicitly. There isn't really an observeable gain to be had here from a speed point, but it helps in avoiding an (uncommon) problem of having a too long commandline passed to dpkg, which we would split up (probably incorrectly).
2016-06-08edsp: drop privileges before executing solversDavid Kalnischkies
Most (if not all) solvers should be able to run perfectly fine without root privileges as they get the entire state they are supposed to work on via stdin and do not perform any action directly, but just pass suggestions on via stdout. The new default is to run them all as _apt hence, but each solver can configure another user if it chooses/must. The security benefits are minimal at best, but it helps preventing silly mistakes (see 35f3ed061f10a25a3fb28bc988fddbb976344c4d) and that is always good. Note that our 'apt' and 'dump' solver already dropped privileges if they had them.
2016-06-08edsp: if logging is requested, do it for internal, tooDavid Kalnischkies
Create and log the EDSP(like) request even if we use the internal resolver.
2016-06-08edsp: if internal is used, keep this decisionDavid Kalnischkies
It wasn't noticeable before, but now with the (optional) logging it can be observed that we decide in the internal path two times if an internal or external solver should be used (and hence with logging, it is attempted twice), so if we are in the internal path call the internal resolver directly, which means those internal methods need to be public – but we can hide them based on the symbol at least.
2016-06-08move 'dump' solver from apt-utils to apt packageDavid Kalnischkies
2016-06-08edsp: optionally store a compressed copy of the last scenarioDavid Kalnischkies
For bugreports and co it could be handy to have the scenario and all the settings used in it around later for inspection for EDSP like protocols. EDSP might not be the most interesting as the user can still interrupt the process before the solution is applied and users tend to have an opinion on the "rightness" of a solution, so it is disabled by default.
2016-06-06edsp: prevent it from trying to write a cacheDavid Kalnischkies
EDSP(-like) protocols are one-shot processes working on data which exists only as long as they run (as they get feed via a pipe), so trying to write a cache for it is pretty pointless, especially as it will usually fail as the cache files tend to be owned by root, but the process is run as a unpriviledged user (either _apt if called by root, otherwise the user of the caller). So this was in fact only observeable with our testcases which run as non-root and the worst which happens is that a valid cache is overridden with an invalid one which the next run will detect and not use.

2016-06-06get right of the hardcoded string-length comparesDavid Kalnischkies
With have better ways to compare, manipulate and work with strings, so use it instead of counting string length by hand with is a wonder it hasn't failed yet. Ignoreable from a changelog perspective as there is no behaviour change. Git-Dch: Ignore
2016-06-05refactor EDSP classes for better internal reuseDavid Kalnischkies
The classes are all marked as hidden, so changing them is no problem ABI wise and will help with introducing protocols similar to EDSP. The change has no observeable behavior difference, its just code juggling. Git-Dch: Ignore
2016-06-04prepare-release: ignore newer version symbolsDavid Kalnischkies
The script takes the version from the changelog, but if it lacks behind and the symbols file already includes symbols tagged for the next version the helper prints incorrect lines as NEW for these symbols, but ideally it shouldn't print them at all as the symbol is already dealt with. Git-Dch: Ignore

2016-06-04edsp: use a stanza based interface for solution writingDavid Kalnischkies
EDSP had a WriteSolution method to write out the entire solution based on the inspection of a given pkgDepCache, but that is rather inflexible both for EDSP itself and for other EDSP like-protocols. It seems better to use a smaller scope in printing just a single stanza based on a given version as there is more reuse potential.
2016-06-04edsp: use an ID mapping for the internal solverDavid Kalnischkies
Currently an EDSP solver gets send basically all versions which means the absolute count is the same, but that might not be true forever (and with the skipping of rc-only versions it kinda is already) and even if it were true, segfaulting on bad input seems wrong.
2016-06-02apt-key: change to / before find to satisfy its CWD needsDavid Kalnischkies
First seen on hurd, but easily reproducible on all systems by removing the 'execution' bit from the current working directory and watching some tests (mostly the no-output expecting tests) fail due to find printing: "find: Failed to restore initial working directory: …" Samuel Thibault says in the bugreport: | To do its work, find first records the $PWD, then goes to | /etc/apt/trusted.gpg.d/ to find the files, and then goes back to $PWD. | | On Linux, getting $PWD from the 700 directory happens to work by luck | (POSIX says that getcwd can return [EACCES]: Search permission was denied | for the current directory, or read or search permission was denied for a | directory above the current directory in the file hierarchy). And going | back to $PWD fails, and thus find returns 1, but at least it emitted its | output. | | On Hurd, getting $PWD from the 700 directory fails, and find thus aborts | immediately, without emitting any output, and thus no keyring is found. | | So, to summarize, the issue is that since apt-get update runs find as a | non-root user, running it from a 700 directory breaks find. Solved as suggested by changing to '/' before running find, with some paranoia extra care taking to ensure the paths we give to find are really absolute paths first (they really should, but TMPDIR=. or a similar Dir::Etc::trustedparts setting could exist somewhere in the wild). The commit takes also the opportunity to make these lines slightly less error ignoring and the two find calls using (mostly) the same parameters. Thanks: Samuel Thibault for 'finding' the culprit! Closes: 826043
2016-06-02ignore std::locale exeception on non-existent "" localeDavid Kalnischkies
In 8b79c94af7f7cf2e5e5342294bc6e5a908cacabf changing to usage of C++ way of setting the locale causes us to be terminated in case of usage of an ungenerated locale as LC_ALL (or similar) – but we don't want to fail here, we just want to carry on as before with setlocale which we call in that case just for good measure.
2016-06-01Pass -fvisibility-inlines-hidden to g++Julian Andres Klode
This reduces the number of symbols by about 10%. Unfortunately, it does not seem to cover all the weird std::vector and friend template expansions. ABI should not brake due to that change: It was never specified before whether an inline symbol was exported or not; so no library could rely on its presence. Instead, the symbols were exported in each library/program needing it and and then merged into a common one by the dynamic linker. Also update the symbol files to account for the removed symbols.

2016-05-29try to detect sudo spawned root-shell in prefixingDavid Kalnischkies
It is a try as the we need to inspect SUDO_COMMAND which could be anything – apt, apt-get, in /usr/bin, in a $DPKG_ROOT "chroot", build from source, aliases, … The best we can do is look if the SHELL variable is equal to the SUDO_COMMAND which would mean a shell was invoked. That isn't fail-safe if different shells are involved as sub-shells have the tendency of not overriding the SHELL so a bash started from within zsh can happily pretend to be still zsh, so we could have a look at /etc/shells for a list, but oh well, we have to stop somewhere I guess. This sudo-prefixing feature is a gimmick after all. Closes: 825742
2016-05-28travis: use gcc-5 instead of gcc(-4.9)David Kalnischkies
The std::put_time and std::get_time introduced in 9febc2b238e1e322dce1f94ecbed46d595893b52 are part of C++11, but not implemented in GCC until version 5. std::put_time could actually be worked around via using the facets put() directly, but get() isn't implemented so that doesn't really help. We require various tools from wily (which also means we can't build apt on Debian stable) already, so requiring gcc-5 is just one more instead of a big step [and an ignoreable change for changelog anyhow]. It also helps in testing what will actually be used (in terms of the c++11 std ABI) instead of the old ABI. Git-Dch: Ignore
2016-05-28look into the right textdomain for apt-utils againDavid Kalnischkies
Broken in e7e10e47476606e3b2274cf66b1e8ea74b236757 by looking always into "apt" while we ship some tools in "apt-utils"…
2016-05-28use std::locale::global instead of setlocaleDavid Kalnischkies
We use a wild mixture of C and C++ ways of generating output, so having a consistent world-view in both styles sounds like a good idea and should help in preventing regressions.
2016-05-28use de-localed std::put_time instead rolling our ownDavid Kalnischkies
2016-05-28avoid changing the global LC_TIME for Release writingDavid Kalnischkies
Using C++ here avoids calling setlocale here which never really was that ideal, but needed to avoid locale specific weekday/month names.
2016-05-28accept only the expected UTC timezones in date parsingDavid Kalnischkies
HTTP/1.1 hardcodes GMT (RFC 7231 §7.1.1.1) and what is good enough for the internet must be good enough for us™ as we reuse the implementation internally to parse (most) dates we encounter in various places like the Release files with their Date and Valid-Until header fields. Implementing a fully timezone aware parser just feels too hard for no effective benefit as it would take 5+ years (= until LTS's are out of fashion) until a repository could use non-UTC dates and expect it to work. Not counting non-apt implementations which might or might not only want to encounter UTC here as well. As a bonus, this eliminates the use of an instance of setlocale in libapt. Closes: 819697
2016-05-27prevent C++ locale number formatting in text APIsDavid Kalnischkies
Setting the C++ locale via std::locale::global(std::locale("")); which would otherwise default to the default C locale (aka: unaffected by setlocale) effects the formatting of numeric types in IO streams, which for output for humans is perfectly sensible, but breaks our many text interfaces used and parsed by us and others without expecting the numbers to be formatted. Closes: #825396
2016-05-27fix and document on the fly compressor configDavid Kalnischkies
libapt allows to configure compressors to be used by its system via configuration implemented in 03bef78461c6f443187b60799402624326843396, but that was never really documented and also only partly working, which also explains why the tests weren't using it…

2016-05-25remove semi-support for different build-dirsDavid Kalnischkies
The debian/rules file tries to guess in which directory it is supposed to be building, but that guess is always ./build – if it wasn't it would fail later as not all rules take alternatives into acount. So, as this is clearly not used lets remove this complexity instead of fixing it up. Git-Dch: Ignore

The embedding is done completely automatic by doxygen and documented to be that way for reasons: /usr/share/doc/doxygen/README.jquery As we can't do anything about it, it is pointless to keep the warning.

The code moving in eb1f04dda07c2b69549ad9fd793cca0e91841b3e moved the acquire stuff above the simulation exit, so before getting locks (and creating/chmod directories) we should be checking if we should actually really do it… [ignore as bugfix of an unreleased commit] Git-Dch: Ignore
2016-05-20refactor EDSP code into EDSP and EDSP-like partsDavid Kalnischkies

2016-05-20edsp: try harder to not generate unneeded error messagesDavid Kalnischkies
The &= introduced in the EDSP-FileFd conversion isn't working to full satisfaction for multiple && clauses as the && has a higher binding than &= has, so that the methods were called even through they shouldn't have because of previous errors. Using variadic functions we can solve this in a slightly cleaner way bringing down the amount of 'broken pipe' errors for the error case of the dump resolver substantially. Git-Dch: Ignore

2016-05-20fail instead of segfault on unreadable config filesDavid Kalnischkies
The report mentions "apt list --upgradable", but there are others which have inconsistent behavior ranging from segfaulting to doing something with the partial (and hence incomplete) data. We had a recent report about sources.list (#818628), this one mentions prefences, the obvious next step is conf files… so the testcase is adapted to check for all three in file and directory versions and run a bunch of commands each time which should all have more or less the same behavior in such a case (aka error out).

2016-05-16document --no- as --show-upgraded is the defaultDavid Kalnischkies
--show-upgraded is the default since 906fbf8886926eeb302332d997c9bd861291e155 so documenting it as if it would be an option having an effect as is feels wrong and we do the same for other options like install-recomends, download, …, too. This commit also removes -u from the documentation, but still supports it in the commandline parsing. Eventually we should deprecate the short option, but for now lets just stop documenting it. Closes: 824456
2016-05-16show final solution in --no-download --fix-missing modeDavid Kalnischkies
This commit moves the creation of the fetcher and with it the calculation of the filenames before the code generation the various lists detailing the solution. This means that simulation comes even so slightly closer to a real run as it will require and parse the package indexes for filenames and queuing of URIs, so that a simulation "using" an unavailable download method actually fails now. The real benefit of this change is through that the rather special but nontheless handy --no-download --fix-missing mode now actually shows what the solution is it will apply to the system rather than the solution it would if it could download all not-downloaded packages.
2016-05-16show globalerrors before asking for confirmationDavid Kalnischkies
Errors cause a kind of automatic no already, but warnings and notices are only displayed at the end of the apt execution even through they could effect the choice of saying yes/no to questions: E.g. if a configuration (file) was ignored you wanted to have an effect or if an external solver you used generated warnings suggesting that the solution might be valid, but bogus non-the-less and similar things. Note that this only moves those messages up to the question if the answer is interactive – not if e.g. -y is used or no question is asked at all so this has an effect only on interactive usage of apt(-get), not script who might be parsing apt output.
